Interpretation and Investigations of Topology Based Routing Protocols Applied in Dynamic System of VANET

Abstract

The intelligent transportation system is necessary for smart connection among vehicles and roadways equipment. Vehicular Ad-hoc Network (VANET) where vehicles are linked together through a wireless link is an emerging research area and gaining attention for this smart connection where each vehicle is a node in the ad-hoc network consists of groups of stationary or moving vehicles. This dynamic system of VANET provides an infrastructure that builds new solution for safety and comfort but this implementation presents a hurdle in the selection and designing of a routing protocol which is capable of providing reliable and efficient transportation of packets. The prior objective of this research is to select and suggest reliable routing protocol and gives a performance assessment of the topology based protocol’s properties in terms of high-density dynamic systems of vehicles i.e., Ad Hoc on-Demand Distance Vector (AODV), Optimized Link State Routing Protocol, Dynamic Source Routing (DSR), and Destination-Sequenced Distance-Vector on the grounds of simulation parameters (packet delivery ratio (PDR), overhead (OH), throughput ratio (TR)). The performance is evaluated using network simulator and mobility simulator the Simulation of Urban Mobility. The result shows that in case of TR and OH, protocol DSR outperforms but in case of PDR, protocol AODV outperforms. From the above, conclusion is that this research will assist the researchers in selecting the better routing protocol in the implementation of dynamic system of VANET infrastructure.
